Take the moment car A starts to accelerate to be the origin. Then car A has position at time <em>t</em>
<em>x</em> = (20.0 m/s) <em>t</em> + 1/2 (2.10 m/s²) <em>t</em>²
and car B's position is given by
<em>x</em> = 300 m + (27.0 m/s) <em>t</em>
<em />
Car A overtakes car B at the moment their positions are equal:
(20.0 m/s) <em>t</em> + 1/2 (2.10 m/s²) <em>t</em>² = 300 m + (27.0 m/s) <em>t</em>
300 m + (7.00 m/s) <em>t</em> - (1.05 m/s²) <em>t</em>² = 0
==> <em>t</em> ≈ 20.6 s
Answer:
Centimeter
Explanation:
We know the measurement is defined as:
1 meter= 100cm
1 cm= 1/100 meter
1 centimeter= 0.01 meter
Therefore, 0.01 meter is equal to 1 cm or 1 centimeter.
The Space Age began on October 4, 1957.
Data Analysis and Conclusion
Answer:
Radius = 0.8235 cm
Density = 0.7265 g/mL
Explanation:
Given that the volume = 2.34 cm³
The volume of the sphere = 
Thus,
<u>r = 0.8235 cm</u>
Volume = 2.34 cm³ = 2.34 mL (1 cm³ = 1 mL)
Mass = 1.7 g
<u>Density = Mass/ Volume = 1.7 g / 2.34 mL = 0.7265 g/mL</u>
